Abstract

A housing assembly for an imaging assembly comprises a housing body comprising at least one passage for accommodating a respective light socket; and a filter integrated with the housing body through which an image sensor looks.

Claims

1. A housing assembly for an imaging assembly, the housing assembly comprising:

a housing body comprising at least one passage for accommodating a respective light socket; and

a filter integrated with the housing body through which an image sensor looks.

2. The housing assembly of claim 1, wherein the housing body comprises a plurality of passages, each passage accommodating a respective light socket.

3. The housing assembly of claim 2, wherein two of said passages are positioned on opposite sides of said filter.

4. The housing assembly of claim 3, wherein one of said passages is positioned above said filter.

5. The housing assembly of claim 4, wherein said one passage is centrally positioned above said filter.

6. The housing assembly of claim 4, wherein said filter is an infrared pass filter.

7. The housing assembly of claim 6, wherein said infrared pass filter has a pass wavelength range of between about 830 nm and 880 nm.

8. The housing assembly of claim 1, wherein said filter is an infrared pass filter.

9. The housing assembly of claim 7, wherein said infrared pass filter has a pass wavelength range of between about 830 nm and 880 nm.

10. The housing assembly of claim 1, further comprising a retro-reflective label disposed on a forward surface of the housing body.

11. The housing assembly of claim 6, further comprising a retro-reflective label disposed on a forward surface of the housing body.

12. The housing assembly of claim 8, further comprising a retro-reflective label disposed on a forward surface of the housing body.

13. The housing assembly of claim 1, wherein the filter and the housing body are formed of injection moldable materials.

14. The housing assembly of claim 1, wherein the socket comprises a closed end through which radiation emitted by a light source accommodated by said socket passes.

15. The housing assembly of claim 14, wherein the closed end comprises at least one of a beam splitter layer and a diffuser layer.

16. The housing assembly of claim 15, wherein the closed end comprises both a beam splitter layer and a diffuser layer.

17. The housing assembly of claim 6, wherein the closed end comprises at least one of a beam splitter layer and a diffuser layer.

18. The housing assembly of claim 17, wherein the closed end comprises both a beam splitter layer and a diffuser layer.

19. The housing assembly of claim 8, wherein the closed end comprises at least one of a beam splitter layer and a diffuser layer.

20. The housing assembly of claim 19, wherein the closed end comprises both a beam splitter layer and a diffuser layer.

21. The housing assembly of claim 10, wherein the closed end comprises at least one of a beam splitter layer and a diffuser layer.

22. The housing assembly of claim 21, wherein the closed end comprises both a beam splitter layer and a diffuser layer.

23. The housing assembly of claim 1, wherein the socket is rotatable within the passage.

24. The housing assembly of claim 23, wherein the socket is rotatable within the passage between indexed positions.

25. The housing assembly of claim 24, wherein the socket and passage carry mating formations.

26. The housing assembly of claim 25, wherein the mating formations comprise a plurality of grooves and a rib.

27. The housing assembly of claim 26, wherein the grooves are formed in a wall surrounding the passage and the rib is carried by the socket.

28. A method of fabricating a housing, assembly of an imaging assembly for use with an interactive input system, the method comprising:

forming a filter in a mold using a first injection; and

forming a housing body around the filter in the mold using a second injection.

29. The method of claim 28, further comprising resetting the mold prior to the step of forming the housing body.

30. The method of claim 28, wherein the filter forming comprises molding the filter using a first material and the housing body forming comprises molding the filter body using a second material.

31. The method of claim 30, wherein the first and second materials are polycarbonate.

32. The method of claim 28, further comprising applying a label to a forward surface and the housing body.

33. The method of claim 29, further comprising applying a label to a formed surface and the housing body.

34. The method of claim 28, wherein the filter forming and housing body forming are performed at a plurality of injection molding locations simultaneously.

35. The method of claim 32, wherein the filter forming and housing body forming are performed at a plurality of injection molding locations simultaneously.
